**Type:**- Function
**Defined in:**- pc.c
- Initialization of a polynomial with cofactors before Gröbner basis computation.
`p`is assumed to be at position`pos`in a set of`total`polynomials. The cofactors refer to this set of polynomials, hence, the appropriate list of cofactors has the unit polynomial at position`pos`and zero at all other positions. **See also:**- Section 3.13.
